KVM: Portability: Split mmu-related static inline functions to mmu.h
Since these functions need to know the details of kvm or kvm_vcpu structure, it can't be put in x86.h. Create mmu.h to hold them. Signed-off-by: Zhang Xiantao <xiantao.zhang@intel.com> Acked-by: Carsten Otte <cotte@de.ibm.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
